Hi,
We have started rolling out Yosemite this week (10.10.2) and an employee mentioned that he can't use new the extensions features like the calculator widget in the today bar and the share menu in safari (It displays No Service). The default extensions simply aren't available in System Preferences. The extensions tab however is accessible.
After some testing I came to the conclusion that this behaviour occurs when I set access restrictions in System Preferences and push the Configuration profile at a user level to the device. Even when I don't block anything (just select the payload) the extensions aren't there.
The only two things that I want to block are the Profiles and Sharing tab.
Anyone else on this? We are running the latest Casper version (9.65).
Cheers
